"Inverse Circular Functions." §4.4 in Handbook This definition can be expressed in terms of the natural This work follows the convention of Abramowitz and Stegun (1972, p. 79) and the Wolfram Language, taking to have range, a discontinuity at, and the branch cut placedĪlong the line segment. There are at least two possible conventions for defining the inverse cotangent. The principal value of the inverse cotangent is implemented in the Wolfram Language Note that in the notation (commonly used in North AmericaĪnd in pocket calculators worldwide), is the cotangent and theĭenotes an inverse function, not the multiplicative Worse yet, the notation is sometimes used for the principal value, with being used for the multivaluedįunction (Abramowitz and Stegun 1972, p. 80). This means that any point in the function becomes. Values of the inverse cotangent, although this distinction is not always made Plotting the inverse of a function is the same method for any function. The variants (e.g., Beyer 1987, p. 141 Bronshtein and Semendyayev,Īre sometimes used to refer to explicit principal (Spanier and Oldham 1987, p. 333 Gradshteyn and Ryzhik 2000, p. 208 JeffreyĢ000, p. 127), that is the inverse function Arccosine function is inverse of the cosine function denoted by cos-1 x. It is represented in the graph as shown below: Graph of arccosine function. Arcsine function is inverse of the sine function denoted by sin-1 x. A function can only have an inverse if it is one-to-one so that no two elements in. Can you always find the inverse of a function Not every function has an inverse. Similarly, for all y in the domain of f (-1), f (f (-1) (y)) y. ![]() (Abramowitz and Stegun 1972, p. 79 Harris and Stocker 1998, p. 311 Jeffrey The graphs of all the inverse trigonometric functions are given as follow. The inverse of a function f is a function f (-1) such that, for all x in the domain of f, f (-1) (f (x)) x. The inverse cotangent is the multivalued function (Zwillinger 1995, p. 465),
